System producing the snow in northwest Wisconsin and eastern Minnesota today is a complex winter system consisting of two surface lows, one over southern Manitoba, and the other over south-central Wisconsin. In addition to that, we have a mid/upper-level trough approaching from the Dakotas. Strong forcing ahead of the trough and lows has led to widespread snow impacting parts of the upper Midwest today with narrow intense snow bands embedded within the larger shield of light snow, with these heavier snow bands being most common from south-central Minnesota into northwest Wisconsin this afternoon.

Gusty northwest winds will develop across the Northland tonight and will linger through the day Wednesday.
Wind gusts of 25 to 40 mph are possible with even stronger wind gusts up to 45 mph near Lake Superior.

HRRR model wind gust forecast thru 6 PM Wednesday.
Another low-pressure system could bring some more snow or possibly a mix bag of precipitation types to the Northland from late Friday afternoon through early Saturday morning.
There is a potential for a few inches of snow with this system, but the overall quick movement of this system should limit the amount of snow that falls in our area later this week.
Stay tuned!
A very amplified pattern sets up over the next two weeks with incredibly high heights (strong ridging) setting up near/over Greenland and also over Alaska. This type of pattern can open up the arctic air flood gates directing it into the upper Midwest.
